because the transmission shaft 2 rotates positively and the threaded area of the transmission shaft 2 is engaged with the inner surface of the rotary ring 21, the rotary ring 21 moves downwards under the action of the threaded area, and the rotary ring 21 moves downwards and drives the activated carbon plate 221 to rotate towards the direction close to the side wall of the purifying cylinder 1 through the first connecting rod 222; as the activated carbon plate 221 rotates, the contact area between the ascending air and the activated carbon plate 221 becomes larger, and at this time, the dust particles with smaller diameters in the ascending air are also removed due to the adsorption action of the activated carbon plate 221; the inflowing air continuously rises to pass through the carbon rods 23 and flow out from gaps among the carbon rods, and the air is further purified due to the adsorption effect of the carbon rods 23; the purified air continuously rises to the bottom of the purification cylinder 1; when the forward and reverse rotation motor starts to rotate reversely, the forced direction of the air inside the purifying cylinder 1 is changed, so that the air inside the purifying cylinder 1 flows downwards and flows out of the purifying cylinder 1 from the first through hole 11, and before the air flows out of the first through hole 11 at the bottom of the purifying cylinder 1, the downwards flowing air is acted by the carbon rod 23, the activated carbon plate 221 and the filter screen 3 again, so that the dust in the air is further removed; therefore, the carbon rod 23, the activated carbon plate 221 and the filter screen 3 repeatedly act on the air flowing into the purifying cylinder 1 through the periodic forward and reverse rotation teleoperation of the forward and reverse rotation motor, so that the air in the vehicle is effectively purified; when the forward and reverse rotation motor is started, mineral water is injected into the purifying box 12 from the liquid guide tube 122 at the top of the purifying box 12, and the purifying box 12 is made of coral ceramic, so that the mineral water reacts with the inner wall of the purifying box 12 to ionize the mineral water; meanwhile, due to the periodic forward and reverse rotation telemotion of the forward and reverse rotation motor, the carbon rod 23 is pressed to move upwards through the second connecting rod when the rotating ring 21 moves upwards in the threaded area of the transmission shaft 2, and the spring between the carbon rod 23 and the top of the purifying cylinder 1 is deformed; when the rotating ring 21 moves downwards and does not press the carbon rod 23 any more, the spring above the carbon rod 23 restores deformation and drives the carbon rod 23 to vibrate up and down; because the carbon rod 23 and the purification box 12 are provided with the second magnet 231 on the opposite surfaces, and the second magnet 231 is contacted with the purification box 12; therefore, the first magnet 123 inside the purifying box 12 also vibrates up and down due to the attraction between the first magnet 123 and the second magnet 231 while the carbon rod 23 vibrates up and down; since the bottom and the top of the first magnet 123 are connected to the inner surface of the purifying box 12 through springs, the first magnet 123 is subjected to the action of the springs when vibrating up and down, so that the vibration frequency is increased, and thus the vibration force is generated; the vibration force generated by the first magnet 123 causes the alkali ionized mineral water to be dissociated and generates water mist and anion gas with physiological activity function, and the anion gas with the water mist flows out of the second through hole 121; the negative ion gas with the water mist flowing out of the second through hole 121 is acted by the negative ion discharge needle 251, the water mist in the negative ion gas is ionized to generate a large amount of hydrogen ions and hydroxyl ions, and a part of the hydrogen ions are obtained into electrons in the ionization process to form hydrogen atoms, so that the content of the negative ions in the negative ion gas is increased, and then the negative ion gas flows out of the purification cylinder 1 from the first through hole 11 under the reverse rotation action of the positive and negative rotation motor; the purification cylinder 1 discharges the anion gas through the effects of the purification box 12 and the anion discharge needle 251, and the anion gas with the function of improving the physiological activity is more beneficial to the health of a user; when the first magnet 123 moves up and down, the rack 124 connected with the first magnet 123 also moves along with the first magnet, the moving rack 124 drives the gear 125 to rotate, and the gear 125 drives the cross-shaped lug 126 to rotate through the supporting shaft, so that the cross-shaped lug 126 rotates along with the gear 125 and acts on the first magnet 123, the vibration frequency of the first magnet 123 is improved, the vibration force generated by the first magnet 123 is larger, and more negative ion gas with physiological activity is dissociated from the alkali ionized mineral water; therefore, the cross-shaped projection 126 arranged at the end part of the gear 125 rotates along with the gear 125, so that the purifying cylinder 1 generates more negative ion gas, which is more beneficial to the health of a user; in addition, the carbon rod 23 moves downwards and simultaneously drives the end part of the elastic rope 225 fixedly connected to the upper surface of the carbon rod 23 to move downwards, the end part of the elastic rope 225 moves to cause the whole elastic rope 225 to be tensioned and pull the dust removing ring 224 through the supporting action of the negative ion discharge needles 251, so that the dust removing ring 224 moves towards the direction close to the transmission shaft 2 on the outer surface of the activated carbon plate 221 and the spring on the dust removing ring 224 is deformed; when the carbon rod 23 moves downwards and starts to move upwards, the elastic rope 225 is loosened, the deformation of the spring on the dust removing ring 224 is recovered, and at the moment, the dust removing ring 224 returns to the original position; the dust removing ring 224 repeatedly moves on the outer surface of the activated carbon plate 221, so that dust particles attached to the surface of the activated carbon plate 221 can be removed, and the activated carbon plate 221 can normally play a role in purifying air.
